Voluntary exit does not appear to use the "--grpc-headers" flag

🐞 Bug Report

Description

When attempting to do a voluntary exit, it always fails because it does not seem to use grpc headers when authorization headers are provided.

Has this worked before in a previous version?

Unknown. However, I am running this on v1.1.0.

🔬 Minimal Reproduction

./validator-v1.1.0-darwin-amd64 \
accounts \
voluntary-exit \
--wallet-dir $WALLET_DIR \
--wallet-password-file $WALLER_PASSWORD \
--public-keys $PUBKEY \
--beacon-rpc-provider $BEACON_RPC \
--tls-cert $TLS_CERT \
--grpc-headers "Authorization=Basic ${TOKEN}"
